摘要
对炸药爆炸条件下,钚气溶胶扩散研究中的源项特性和扩散模型进行了总结,并对扩散模型的特点进行了评述和对比。根据事故应急响应要求对扩散计算模型的选择进行了相关讨论,同时提出钚气溶胶扩散研究中值得关注的问题。
The source-term and dispersal models of plutonium aerosol in atmosphere are summarized in this paper, including the calculating method for cloud top height and cloud radius generated by explosive sources. The plutonium-aerosol parameters are described by the ＂Roller Coaster＂ test. The dispersal mod- els include DIFOUT model, MACCS2 model, ERAD model, FEM3 model and ADAPT/LODI model. The characteristics of these models are analyzed and compared. Some aspects of the plutonium aerosol dispersal in atmosphere are discussed, such as the aerosol dispersal induced by abnormal fire.
